The teacher is actually correct.

Say you have a board with a surface of 1 square foot. To cut it in half, you would have to make a cut of 1 foot long. This takes 10 minutes, so your cutting speed is .1 foot per minute.
To saw one of the remaining pieces (which are both .5 x 1 foot) in half, you'd only have to cut .5 foot, which would take 5 minutes.
QED you're retarded.

Why the **** would you cut a board longways? If it takes you 10 minutes to cut a 2x4 into two pieces, they're still 2x4s. The thickness, and therefore the time taken to cut it, doesn't change. Ten minutes per cut. End of story.
